HOlSTlNG-BUCKET.

SPECIFICATION forming part of Letters Patent No. 531,734, dated January1, 1895.

Application filed July 14,18 94. Serial No. 517,519. (No model.)

To all 1072,0122 it may concern..-

Be it known that I, THOMAS F. MOORE, a citizen of the United States,residing at Buffalo, county of Erie, and State of New York, haveinvented a new and useful Improvement in Hoisting-Buckets, of which thefollowing is a specification.

This invention relates more especially to the hoisting buckets which areemployed in connection with hoisting and conveying apparatus for diggingsewer trenches and which are provided with a hinged bottom.

The principal object of my invention is to provide the bottom of thebucket withasimple lock or latch which is easily operated and whichpresents no projecting parts on the out side of the bucket that areliable to catch against objects and prematurely release the bottom.

A further object of the invention is to improve the construction of thehinges which connect the bottom with the bucket.

In the accompanying drawings: Figure 1 is a sectional perspective viewof my improved hoisting bucket. Fig. 2 isabottom plan view thereof. Fig.3 is a sectional elevation of the upper portion of the lock and theadjacent portions of the bucket, on an enlarged scale. Fig. i is asimilar View of the lower portion of the lock. Fig. 5 is a longitudinalsection, on an enlarged scale, of one of the hinges of the bottom.

Like letters of reference refer to like parts in the several figures.

A represents the body of the bucket, which is preferably constructed ofsheet metal and reinforced at its upper end by a band a.

Bis a horizontal stay-bar connecting the side walls of the bucket nearthe upper edge thereof, and B is a similar stay-bar connecting the sidewalls near the lower end of the bucket. These stay-bars are preferablyconstructed of wrought iron and their end portions are split verticallyand spread in the form of angular lips or flanges b which are riveted tothe inner sides of the side walls, as shown in Fig. l.

h is an eye secured to the upper stay-bar for receiving the hook of theusual fallblock.

G is the bottom which is hinged at one edge to the lower end of thebucket, and D is a U- shaped cleat or stifiening bar secured to theunder side of the bottom and consisting of angle iron.

0 represents the perforated knuckles of the hinges which are secured tothe body of the bucket and c the hinge pins.

The base flange of the angle iron D is cut away adjacent'to the knuckles0 while the other or vertical flange of the angle iron projects beyondthe adjacent edge of the bottom so as to form the hinge members orknuckles of the bottom. The knuckles cl are preferably reinforced bybars or plates d riveted to the inner sides thereof and the latter andthe knuckles are provided with openings for the passage of thehinge-pins, as shown in Fig. 5. By thus combining the knuckles of thebottom with the cleat a strong and reliable hinge connection is obtainedwhich is comparatively inexpensive.

The lock whereby the hinged bottom is held in its closed positionconsists of an upright rock shaft E arranged within the bucket andhaving at its lower end a toe or laterally projecting latch e whichengages in a horizontal loopf secured to the upper side of the hingedbottom near its free edge, as shown in Figs. 1 and 4. The rock shaft Eis journaled in bearings which are preferably formed partly by therecesses e at the junction of the staybar flanges B and Band partly bythe adjacent side walls of the bucket, as shown in Fig. 1, wherebyseparate bearings for the shaft are dispensed with and the cost of thebucket is reduced. The upper endof the rock shaft projects above theupper edge of the bucket and is made square or flat-sided to receive adetachable wrench or hand lever G for turning the shaft. Verticaldisplacement of the rock shaft is prevented by a screw-nut h applied toan external screw-thread formed on the projecting portion of the shaft,below its square end, and abutting against the upper side of theadjacent stay bar B. This nut, while permitting the shaft to turnfreely, enables the same to be adjusted vertically for properlyregistering its locking latch with the loop of the hinged bottom. Upongiving the rock shaft a sufficient turn, the toe at its lower end iswithdrawn from the loop of the bottom, thereby allowing the latter toswing open and discharge the contents of the bucket. After locking thehinged bottom and before again lowering the discharged bucket, thewrench of the shaft is removed so as not to obstruct the movements ofthe bucket.

'i are stops formed of angle iron and secured to the inside of thebucket at the corners near the bottom and against which the bottom ofthe bucket abuts upon closing the same.

The loop of the bottom is preferably arranged obliquely or" at an angleto the side wall of the bucket, as shown in Fig. 1. By this arrangementthe space between the front end of the loop and the adjacent side wallof the bucket is widened, thus enabling the toe of the rock shaft topush aside any hard obstruction that may lodge between the loop and theside wall and insuring the free operation of the lock.

By constructing the lock as herein shown and described, its parts areall located inside the bucket and the lock, therefore, offers noprojections which by catching against surrounding objects are liable tocause unlocking of the hinged bottom and allow a premature discharge ofthe buckets contents, or which are liable to strike parts of theconveying car or other apparatus and interfere with the movements of thebucket.

I claim as my invention 1. The combination with a hoisting bucketprovided with a hinged bottom and having one of its upright wallsprovided with internal shaft bearings, of a horizontal loop secured tothe upper side of the hinged bottom near the outer edge thereof, and anupright rock shaft journaled in said bearings, extending to the top ofthe bucket and provided at its lower end with a lateral toe engagingwith the loop of the hinged bottom, substantially as set forth.

2. The combination with the bucket having cross stays provided withsplit end portions forming flanges which are secured to the Walls of thebucket, of the hinged bot tom having a loop, and an upright rock shaftjournaled in the recesses formed between the split end portions of saidstay-bars and the adjacent wall of the bucket, and having at its lowerend a toe which engages in the loop of the hinged bottom, substantiallyas set forth.

Witness my hand this 26th day of June, 189i.

THOMAS F. MOORE.
